Manual of this product.
The SLM800S/1200S/1500S Series is a high quality ultrasonic level measurement system which provides non-contact level measurement for liquids and solids. Easy calibration and maintenance free "fit and forget" performance mean that you can install the SLM1000 Series rapidly and with confidence.
The SLM800S/1200S/1500S operates on the principle of timing the echo received from a measured pulse of sound transmitted in air and uses "state of the art" echo extraction technology. The SLM800S/1200S/1500S Series is comprised of a controller and a separate remote sensor.
Features
- Simple calibration
- 5 Relay outputs for control
- RS-485 or RS-232C digital output options
- Explosion proof sensor construction
- Large measuring range up to 15m
